PENGEMBANGAN PAPAN SEMEN KOMPOSIT BERKUALITAS TINGGI BERBAHAN BAKU BAMBU

ABSTRAK AGROKOMPLEKS 2008Bamboo is one alternative resources which high potency as raw materials for cement board. In this study, the age effect of bamboo on the properties of cement board and properties comparation of cement board made from green and used bamboo were investigated. The age of bamboo consist of three group : young bamboo (1-2 years old), mature bamboo (3-4 years old) and old bamboo (> 4 years old). Two Indonesian bamboo species, namely ; ater bamboo (Gigantochloa atter) and betung bamboo (Dendrocalamus asper) and 2% CaCl2 based on cement weight were used for manufacturing cement board.. The result of this study are as follows :, 1) The mature bamboo has lowest modulus of rupture compared to the other types of board, while its modulus of elasticity tend to decrease with the increasing of bamboo age. 2) The modulus of rupture of cement board made from ater bamboo was equal with betung bamboo relatively, while its modulus of elasticity tend to inferior compared to cement board made from betung bamboo. 3) The dimensional stability and modulus of rupture of cement board made from used bamboo more superior compared to cement board made from green bamboo, while its modulus of elasticity more inferior
